Sierra Pacific Engineering and Products has added a new adjustable rod guide to their product line. It is the 710AL, it is not possible to weld steel to aluminum so SPEP has created a new rod guide in aluminum. Now an aluminum NEMA enclosure can be produced with more aluminum internal components. This allows for easy production of enclosures as well as a more corrosion resistant system. SPEP has received an ISO 9000 certification so high quality parts can always be guaranteed.
